Abstract

The reactions of OsH(Ph)(CO)L 2 (L = P tBu 2Me) with HSiMe 3, H 2SiPh 2 or H 3SiPh produce benzene and OsH 3(silyl)(CO)L 2, which is characterized as a fac-H 3OsP 3 shape capped on the H 3 face by the silyl group. For H 2SiPh 2 and H 3SiPh, these reactions are shown proceed through an intermediate Os(H) 2(silylene)(CO)L 2 species. OsHF(CO)L 2 reacts with these silanes to give the same OsH 3 product (and silyl-F). These reactions can be combined to effect osmium catalysis of conversion of SiH + H 2CCHF to fluorosilane and H 2CCH 2 from OsH 3(SiMe 3)(CO)L 2, or from the catalyst precursor OsHF(CO)L 2.
